Description
Technical field
The present invention relates to one and can be used for bonding between object in building materials and industrial and mining establishment and daily life, matrix reinforcing
Produce with composite and the compositions of object surface protection, especially comprise the honest and clean of waterglass, isocyanates and performed polymer thereof
Valency two-component composition.
Background technology
Waterglass is a kind of cheap, inorganic sizing material of environmental protection, but is used as adhesive or dip-coating and laminates composite
Its adhesive strength of sizing material and resistance to water all difficulties reach satisfaction, although can be by adding prodan and/or metal oxygen
Compounds etc. shorten hardening time and increase intensity, but because of its intrinsic fragility be difficult to use in metal and metal, metal with nonmetal with
And between nonmetal, require higher occasion；And the most also can be because of the migration of small-molecule substance with containing silica-based with its coating prepared
Plant ecology effect on material has occurred that halogen returns frost and strips off.Adding silane coupler in waterglass, to seem to improve it bonding
Property, due to alkalescence and the aqueous feature of waterglass, there is subtle relations and complex reaction between compositions, in addition water in storage process
In glass ingredient, single silicon of nano-scale and the content of oligomeric silicon itself can be gradually lowered, the most at relatively high temperatures after mixing
Easily forming complicated polymer, its adhesion strength is the most disappointing.
The adhesive being currently used for bonding construction material, ornament materials, door core and panel mostly is polyurethane foam glue, producer
Require that its positive tensile bond strength is not less than 0.5MPa.It is mainly PEPA or polyether polyol is anti-with polyisocyanates
The base polyurethane prepolymer for use as containing remaining end NCO group that should be formed, the most also dichloromethane added with proper catalyst and about 50% are made
Diluent.Domestic foamed glue NCO general content about 3%--6%, flexible is good, and adhesive strength is higher, advantage easy to use.But
Foamed glue price is higher, and colloid is inflammable, burning produce dense black smoke release toxic gas, sizing material use in can discharge have in a large number latent
At the dichloromethane of carcinogenic danger, health risk, hydrogen chloride can be produced under dichloromethane wet heat condition, deposit potential corrosion hazards
Property.Although many research institutions and enterprise attempt to substitute foamed glue with lower-cost inorganic sizing material or water-base cement, but at metal
All the time fail solution initial bonding strength bonding with between metal and between metal with timber and other rigid non-metallic is weak, adhesion strength
Little, it is long that surface drying does solid work the time, and glue-line fragility is big, and water-fast weatherability is poor, the technical barrier of the water suction moisture absorption.Owing to water content height solidifies
Slowly, water-base cement is also easy to cause metal erosion.
European patent EP 03010871.9 and Chinese patent CN1788064A disclose " using of Huntsman International LLC
Polyisocyanates dispensing in filled board " patent application, it pass through alkali metal silicate solutions and the polyisocyanates system of reacting
The standby binding agent being applicable to A2 level fire Euro-classification filled board, the combustion heat is not higher than 25MJ/kg, flame-proof environmental protection, but timber-
Between iron and steel, adhesive strength and stability are undesirable；Chinese patent CN103627330A invention disclosed application " a kind of compound adhesive
Material ", by add in waterglass after organic synergist and/or additive again with polyisocyanates and polyester thereof and or polyethers many
Unit's alcohol performed polymer adapted, improves adhesion strength and the weatherability of sizing material, but viscosity is bigger than normal, especially low temp area and low warm season
Joint viscosity is bigger, is unsuitable for the more low viscous occasion of requirement.
Theory is said, reduces the addition of inorganic filler, is likely in the case of viscosity is less big by adding coupling agent
Obtain bigger adhesion strength.Coupling agent can improve interfacial characteristics between filler and macromolecular material, exists in its molecular structure
A kind of can be with inorganic filler with macromolecule matrix generation chemical reaction or the functional group of the best compatibility and another kind
Form the functional group of chemical bond.Due to inorganic filler and high-polymer molecular in chemical constitution and physical aspect the most different, lack
Weary affinity, coupling agent can improve the interface performance between macromolecular material and filler, improves the cohesive at interface.Numerous
Coupling agent kind in, silane coupling agent is one of kind of studying the earliest and being widely used.Leading to of silane coupler
Formula can be written as RSiX3, and wherein R is to have the active function groups of affinity and respond, such as vinyl chloride third with polymer molecule
Base, epoxy radicals, methylacryloyl, amido and sulfydryl etc.；X is the alkoxyl that can hydrolyze, such as methoxyl group, ethyoxyl etc..Silicon
The using method of alkane coupling agent mainly has surface pretreatment methods and directly joining method, and the former is the coupling agent treatment filler with dilution
Surface, the latter is when resin and filler premix, and adds the stock solution of coupling agent.Silane coupler can be added directly into gluing
In agent component, general addition is the 1～5% of matrix resin amount.Relying on the diffusion of molecule after gluing, coupling agent molecule moves
Move on to produce at bonding interface coupled action.For needing the adhesive of solidification, placement a period of time is needed to carry out after gluing again solid
Change, so that coupling agent completes transition process, preferable effect can be obtained.Silane coupler wiring solution-forming, beneficially silane are even
Connection agent is in the dispersion of material surface, and the solution that solvent is water and alcohol is configured to, solution is generally 20% silane, 72% alcohol, 8% water, silicon
Alkane hydrolysis rate is relevant with pH value, and neutrality is the slowest, and meta-acid, meta-alkali are the most very fast.After silane hydrolyzate, it is impossible to deposit for a long time, now join existing
With, preferably it was finished in one hour.The decomposition of coupling agent can be accelerated due to alkaline aqueous solution and promote polymeric formation thus
Coupling agent is caused to lose effect.But, inventor once tried out most promising γ-(2,3-epoxy the third oxygen) propyl group trimethoxy
The kinds of surface activating agent such as base silane, gamma-mercaptopropyltriethoxysilane, does not reach desired effects, the most disappointed.
As double-component glue, waterglass is stronger alkaline aqueous solution, and simple test it be easy to show that, adds many in waterglass
Silane coupler, owing to the particularity of waterglass and the complexity experimental result of double-component are the most disappointed.Although adding in B component
Enter some silane coupler and have certain reinforced effects, but add improper being prone to and lose effect.
For solving the problems referred to above, inventor has carried out trying to explore and lot of experiments in the environment of difficult, and result is made us
Inspire, unexpectedly.
